ABSTRACT:
An intake system delivers air into cylinders of an internal combustion engine which are divided into two groups. The cylinders in each group are arranged in one and the same row so that adjoining cylinders in each row do not fire one after another. The intake system has conflux chambers for the cylinder rows, connected to the cylinders by intake passages, and also interconnected to each other by a communication passage having a valve. First and second resonant passages are each connected at one end to the respective conflux chambers and are joined together to communicate with each other at another end, opposite to the one end, in a location at which a throttle body is located. The first resonant passage has a connection point with one conflux chamber closer to an interconnection between both the conflux chambers than a connection point in a lengthwise direction of the second resonant passage with another conflux chamber.
